We all want to make an educated decision whenever possible. But, as Psychology Today points out, the more we learn, the harder it is to make a decision. Worse, we might actually make worse decisions when we have more information at hand.

First off, we're very good at overvaluing things that don't matter, and we want to fill in gaps of information with something, even if it's not important:

The human mind hates uncertainty. Uncertainty implies volatility, randomness, and danger. When we notice information is missing, our brain raises a metaphorical red flag and says, "Pay attention. This could be important..." When data is missing, we overestimate its value. Our mind assumes that since we are expending resources locating information, it must be useful.
